The roller device 51 is mounted at a position where the roller 51 is in contact with the flat portion of the arm support rail device 25 without any gap, and the plate-shaped member 50 functions as a leaf spring that is elastically deformed when the roller 51 at the tip gets over a projection or the like. I do.

  FIG. 5 is an explanatory diagram showing an operation when the target device is mounted using the remote attaching / detaching device of the present invention. First, in the vicinity of the center of the rail 46 for the ring support device, the holding ring device 20 holding the target device 30 is arranged with the center axis of the ring support device 40 using any support device (not shown).

  Next, the driving device 47 is driven until the roller 51 at the tip of the support arm 41 of the ring support device 40 and the second concave portion 66 of the arm support rail device 25 of the holding ring device 20 are engaged, and the ring support is performed. The device 40 is moved toward the retaining ring device 20. Since the holding ring device 20 is now supported by the four support arms 41 of the ring support device 40, any support device (not shown) of the holding ring device 20 is removed. This state is shown in FIG.

  Next, the retaining ring device 20 was supported until the rollers 36 of the retaining ring device 20 climbed over the first protrusions 60 of the two side rail devices 13 and 14 of the frame 10 and engaged with the first concave portions 61. The ring support device 40 is moved. At this time, the ring support device 40 pushes the third protrusion 67 of the holding ring device 20 via the roller 51 at the end of the arm 41, but the total force C (hereinafter referred to as C) required to get over the first protrusion 60 C) is adjusted to be smaller (C <B) than the total force B required to get over the third protrusion 67 (hereinafter referred to as B) (C <B). Reaches the first recess 61. At this position, the ring support device 40 is stopped. This state is shown in FIG.

  Next, when the ring support device 40 is moved away (retracted) from the frame 10 from the state shown in FIG. 5B, the total force C over the first protrusion 60 is larger than the total force A over the second protrusion 65. Is adjusted so as to be larger (C> A), so that the roller 51 at the leading end is separated from the concave portion 66 and rides over the second protrusion 65, so that the ring support device 40 and the holding ring device 20 are separated. This completes the work of attaching the holding ring device 20 to the frame 10. This state is shown in FIG.

  FIG. 6 is an explanatory diagram showing an operation when the target device is detached using the remote attaching / detaching device of the present invention. FIG. 6A shows the same state as FIG. 5C. From this state, the ring support device 40 is moved toward the holding ring device 20. Then, the roller 51 at the tip of the support arm 41 of the ring support device 40 and the second concave portion 66 of the arm support rail device 25 of the holding ring device 20 are engaged. This state is the same as the state of FIG.

  However, when detaching, the ring support device 40 is further moved toward the holding ring device 20 from this state. Then, the total force B required to get over the third protrusion 67 is larger than the total force B, and the roller 51 at the leading end gets over the third protrusion 67 and advances to a position where it comes into contact with the end face of the rail 25. At this position, the ring support device 40 is stopped. This state is shown in FIG.

  Next, when the ring support device 40 is retracted from the frame 10 from the state of FIG. 6B, the total force B over the third protrusion 67 is larger than the total force C over the first protrusion 60 ( B> C), the roller 36 is separated from the concave portion 61 and climbs over the first protrusion 60, and the frame 10 and the holding ring device 20 are separated. Thus, the operation of separating the holding ring device 20 from the frame 10 is completed. This state is shown in FIG. The holding ring device 20 can be separated from the ring support device 40 by pulling with a force of B or more.

  As described above, since the force required for each roller to get over the projection needs to satisfy B> C> A, the force of the plate-like members 37 and 50 serving as leaf springs so that B> C> A is satisfied. The shape and material such as width, length and thickness, or the heights of the first to third protrusions are adjusted.

  Specifically, for example, when the pressing forces of the spring-loaded rollers are all the same, four rollers are involved in the forces A and B, and two rollers are involved in the force C. Therefore, in order to satisfy C> A, the height of the protrusion 65 related to A is reduced to, for example, about １ ／ of the height of the protrusion related to C. If the heights of the protrusions relating to B and C are the same, then B> C, so the heights may be the same. In addition, when the roller 51 at the front end gets over the protrusion 67 and is in contact with the end surface of the rail device 25, a greater force is required to get over the protrusion 67 when returning.

  With the above-described configuration, the remote attachment / detachment device of the present invention can attach or detach the holding ring device 20 to / from the frame 10 simply by moving the ring support device 40 forward or backward to a predetermined position.

  The embodiments have been disclosed above, but the following modifications are also conceivable in the present invention. In the embodiment, the example in which the two first rail devices are provided on the left and right side surfaces is disclosed. However, two third rail devices may be provided with protrusions and recesses to have the function of the first rail device. .

  The remote attachment / detachment device according to the present invention can be applied to any device that needs to be detached by operating the device from a remote place.
